IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent N0. 44.283, dated September20, 1864.

.To all whom, it may concern.-

Be it known that I, E. U. CLEVELAND, of \Vorcester, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Spinning lliachinery and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figures l and 2 represent an elevation of asection of. a spinning-jack which contains my improvements, the line ofsection being the red line x, Fig. 3, the carriage being the partdesignated by the Fig. 2. Fig. 3 represents a sectional elevation of theback part of the jack as seen from the front of the machine, containingthe posts and the arch which holds the clock, the line of section beingthe red line y in Fig. 2. Figs. et and 5 are views of detailed parts.Fig. 7 is an elevation of a part of the carriage, showing one of the tindrums which .give motion to the spindles, and the shaft and hand-wheelby which the tin drums are set in motion; and Fig. 6 is a sectional viewof one of the bearings of said shaft and hand-wheel. Fig. 8 is aperspective view of that part ofthe jack which contains the clock andthe mechanism by which it is operated, and also ot' a section ot` thecarriage.

Similar letters of reference indicate corresponding parts.

My invention consists in certain improvements in the constructionofjaeks, whereby I am enabled to place the clock for indicating theamount ot' work done and its mechanism within the frame of the jack, andalso in the construction of the mechanism for causing the clock toindicate the work of the jack, and in the manner of operating saidmechanism, and also in the manner ofconstructin g and adjusting thebearings of the shaft which drives the shaft of the tin cylinders.

Figs. l and 2 represent the framing of'an ordnary jack, and A A are thecenter' and righthand rails on which the carriage BG runs in and out,the other rail being excluded by the section.

C2 represents the upright posts and arch which in my improvements aresubstituted for the ordinary posts and their girt, and for theadditional 'trame and case, sometimes called the clock-post,77 intendedto hold the clock and its actuating mechanism. The arch and posts C2 arein myimprovements made hollow, so as to contain the mechanism they areto sustain. The right-hand post()2 is left open on its outer orright-hand side, but the other post is to be closed by a removablecover, C3. The inner face of the arch is also covered by a door, whichis represented in place in Fig. l and removed in Figs. 3 and S. Thecavity of the arch communicates with that of the post. as shown, so thatthey are continuations of each other. The clock is placed beneath thecrown ofthe arch, and an arbor passing through its center is armed witha toothed wheel, which takes into a worm on a horizontal shaft, K, whichis xed in proper bearings beneath the dial of the clock. A ratchetwheel,K, is secured to the lefthand end ot the horizontal shaft K', and itsreturn or backward rotationis prevented bythe springdetent I. Theratchet-wheel is rotated in one direction by means of a pawl, h, whichis sc cured in two bearings, through which it movi s vertically upward,being held in its normal position by a pin or dog, .10, on its shankresting onthe lower bearing. A spring about its shank rests ou or issecured to the pin, and its upper end bears against the upper of the twobearings, the office of the 'sprin g being to return the pawl to itsnormal position. The pawl his in line over, but not in contact with, thetop of a vertical lifter, C, whose shape is shown in Figs. 1,3, 4, 5,and S, and which extends below the line of the shaft A2, so that it maybe conveniently operated by the devices I use for lifting it. Near itsupper end it carries a horizontal arm, a3, which carries a loose toothedwheel, d,whosefaceis perforated by an annular row ot' holes near itscircumference, which are to receive pins f, whose enlarged heads areclamped between the toothed wheel and a clamp or washer, g, which issecured upon the end of the arm I have shown two pins in holes about onopposite sides of the wheel, so that when the wheel L rotates itsrotation will continue during onehalf a revolution before one of itspins comes against the plate e. The back plate of the post C2 is slottedto make room for the arm a and the plate e, the latter being ofirregular form and the greater part of itbeing contained within thepost. The vertical lifter O rests upon the back rail of the frame A whenat rest. A curved toe, c', projects from the lifter C through the frontof the post G2 at about the level of the carriage BG, by means of whichthe lifter is raised oft' the rail when the friction-roll or arm c ofthecarriage strikes against the. toe. An arm, D', projects from the lifterat its lower end, passing through a slot in the back of the post C2 andresting in one arm of a double crank, af, which is secured to anadjustable bracket, 1, secured to an arm extending from the post. Theother arm of the crank takes hold of the belt-shipper ct'.-

A2 is the main shaft, with its driving and fast-and-loose pulleyssupported upon brackets fast to the posts. The upper part of the lifterU is enlarged, as shown in Figs. 4, 5, and 8, so that it may be formedwith a shoulder, c', which shall rest at certain times upon the centralraised part of the plate c. Thisplate e is loose in the post C2, beingfitted so that its ends shall slide freely through the sides of the postC2, and permit its highest part, c, which s at right angles with thearms e2, to slide beneath the shoulder of the lifter. A spring,j,'attached to the inside of the cover C, bears constan tl y against theface of the plate e, as shown in Fig. 5, forcing it against the lifterand under its shoulder c' and holding it there. Vhen the friction rollor arm c comes.

in contact with the toe c' on its under side, the lifter C rises easilyuntil the compression of the coiled spring around the pawl h becomes sogreat as to partially check the momentum ot' the carriage in its.backward movement, thereby preventing a shock to the jack-carriage whenbrought against the stops or bunter-s7 previous to a return movement, ora draw, so called.

Upon the front of the back rail of the frame is an ad j ustable bracket,r', which carries a double crank, 02, whose outer arm,0', extends towardthe carriage B6, so as to be struck by its arm or friction-roll o whenrunning in. This crank is by this means caused to rock, thereby movingthe slide F of the box E' te the right, by means of the pin n' of theslide resting in a slot in the. vertical arm of the crank o2. The box E'is supported between the posts G2, and carries brackets, which furnishbearings for a shaft, a, back of the frame. This shaft. is driven by abelt running from pulley AG over its pulley q. It has a bevelgear, p,secured on it in such a position as to be at certain times engaged withthe bevelpinion p' on the cross-shaft 8, which latter reaches from therail V of the frame over the box E, its bearin g at its outer end beingfast to the slide F in an adjustable box, so that this end of the shaftwill move with the slide without cramping the bearing. The shaft 8carries a worm, o, at about the center of its length, and a bevel-gear,l0, on its inner end, the latter engaging with the bevel-gear 11 on theshaft l2. The shaft l2 extends the whole length of the j ack and drivesthe parallel shalt l5 by a train of gearing shown in Fin. 1. The

drawing-rolls 14 are supported upon these shafts and are rotated by themby frictional contact. ,The shaft 12 also drives the shaft which carriesthe roping spool-drums 4 by gearing on the outside ofthe framing; but asthese parts are not changed by my improvements, I have not shown them infull. An upright arm, H, borne by a bracket secured to the box E',carries a toothed wheel, I, perforated and armed with two pins and aclamp or washer, J2, in all respects like those which are xed to the armai above mentioned. When the worm o on the shaft 8 engages with it, itwill rotate until one of its pins strikes the spring-stop J', andthereby releases the slide F, and allows it to move back to its normalposition to theleft,carrying with itthe shaft 8, and thus disengagingthe worm o from the toothed wheel I, and the bevel-wheel p' from. thebevel-gearp. The slide F is locked in its position, when moved to theright by the crank o2, by a pin within the box E', which is secured tothe arm J', and which is constantly pressed against a notched projectionfrom the slide by a spring secured to the outer side of the box. Aspiral spring fastened to the slide within the box draws it constantlyto the left.

The operation of these parts (such of them as are contained within thebox E' not being shown) is as follows: The pressure ofthe fric tion rollor arm o throws the slide to the right, when it is locked in thatposition by tl e pin on the inner end of the arm J', which is thusthrown outto an advanced position under the pin-wheel I. This movementof the slide causes the bevel-gears p' and p to engage, as well as theworm o and wheel I, and the toothed pin-wheel I I is thereby caused torevolve until one of its pins strikes aga-inst the arm J', therebypushing it inward and unlocking it from the slide F, when the spiralspring (not shown) on the bottom of the slide draws it to the left,thereby disengaging the bevel-gears p' and p and the worm o and wheel II. The rotation of the shaft 8 is for the purpose of giving the requiredrotation to the draw-rollers lying upon shafts l2 and l5, to enable themat the proper time to draw off a supply of roping from theroping-spools. The left end of the shaft n carries a worm, S, whichengages the toothed pin-wheel d whenever it is carried to its highestposition by the upward movement of the lifter C, the operation being asfollows: Vhen the carriage has about completed its running-in motion,its arm c strikes the toe c' and carries up the lifter C to the positionshown in Figs. 4 and 5, where it is locked by the sliding piece c, whichis then thrown beneath its shoulder c' by the pressure of the spring j.This movement of the lifter also changes the belt by means of the cranka and shipper a'. The lifter carries the toothed wheel al up until itengages with the worm S, which sets it in motion. The 'upward movementof the lifter C drives the pawl h against the ratchet-wheel K androtates it the distance of one tooth, thereby advancing the index ormoving the dial according as one or the other is connected to thespur-wheel which enga-ges with the Worm on shaft K. The toothed wheel drotates until one of its pins, striking against the edge of the looseplate c, overcomes the pressure of the spring j and slides the platefrom beneath the shoulder of the lifter O, which then falls by gravityand the force of the spiral spring on pawl h to its lowest position.

The tin cylinders AO, which drive the spindles, reqpire frequentadjustment backward or forward to admit of new bands and to conipensatefor expansion or contraction in the flexible bands. This could never bedone in jacks as they are now usually constructed without making thegears which connected their shaft to the. shaft of the hand-wheel tobind. I have invented a method of obviating this difliculty, as follows:H is a journalbox, which is fastened to each end of the frame of thecarriage at W,so that it can be moved about it as a fulcrum. A slot, W',is cut across the box to allow the passage of a bindingscrew, wherebythe box is fixed in any position desired. A bracket, J, is fixed to theframe alongside of the journal-box, through which an adjusting screw,K2, works to bear against the inner edge of the box. The gearwhecls E ofthe drum or Vtin-cylinder shaft meshes with the gear E of the hand-wheelshaft B2, as seen in Fig. 7, and both these shafts are supported inboxes springing from a curved adjustable bracket, B5. (Seen in Fig. 7.)These shafts are so secured within their boxes that they have no endwisemotion therein, and it follows that when the bracket which supports theboxes is adjusted in any direction the shafts will be maintained intheir relative positions so that their gears cannot bind. W hen theshaft B', which carries the tin cylindeis, is moved toward or away fromthe spindle-rail, the shaft B2 will have an endwise movement to the sameextent. To allow of this endwise movement of the shaft B2, I haveconstructed the upper bearing for said shaft in the following manner: Aball, 1, slipped upon the shaft and free to move thereon, rests in asocket in a bracket or bearing, B3, whose upper half is removable, andwhen in position covers the shaft for the greater portion of its length.

Instead of the ball-and-socket joint I propose to substitute anotherform of bearing for this end of the hand-Wheel shaft, to accomplish thesame result-to wit, a close or quill box with trnnnions, as shown inFig. 9, the quill resting upon the trunnions and yielding freely to anychange of position required of the hand-wheel shaft. The quill is tobeheld in place by a cap, the saine as in the case of the ball-joint.NVe now construct this part of our invention in the way last described.

I claim as new and desire to secure by Letters Patent- 1. Inclosing thelifter C and the clock and their appurtenances within the arch and oneof the posts of the frame substantiallyY as described.

2. rlhe locking-slide c, constructed and operated substantially asshown, for locking the lifter G.

3. The lifter C, for operating the clock, constructed and operatedsubstantially as shown.

4t. Adjusting the relative positions of the hand-wheel shaft and thetin-cylinder shaft in the manner substantially as described.

5. rlhe combination of the bearing of the hand-wheel shaft with themeans employed for adjusting the inner end of the shaft, substantiallyas described.
